mod(mdg4)02/+ suppresses the variegation of lt due to In(2LR)ltG10 (seen in In(2LR)ltG10/Df(2L)lt10 animals derived from lt16/Df(2L)lt10 females), so that the percentage of pigmented Malpighian tubule cells is increased in the double mutant larvae. mod(mdg4)02/+ suppresses the variegation of lt due to In(2L)ltX2 (seen in In(2L)ltX2/Df(2L)lt10 animals derived from lt16/Df(2L)lt10 females), so that the percentage of pigmented Malpighian tubule cells is increased in the double mutant larvae. mod(mdg4)02/+ does not suppress the variegation of lt due to T(2;3)ltX13 (seen in T(2;3)ltX13/Df(2L)lt10 animals derived from lt16/Df(2L)lt10 females); there is no significant change in the percentage of pigmented Malpighian tubule. mod(mdg4)02/+ suppresses the variegation of lt due to In(2LR)ltG10 (seen in In(2LR)ltG10/lt1 animals), so that the amount of eye pigment is increased in the double mutant adults.

Enhances the variegation in, i.e. reduces the eye pigmentation of, In(1)wm4h, Su(var)2-11 males.

One copy of Dvir\mod(mdg4)t11.5 can rescue the lethality of mod(mdg4)02 homozygotes, with the degree of rescue depending on the P{Dvir\mod(mdg4)t11.5} line used (26.6% and 79.0% viability has been seen). Two copies of Dvir\mod(mdg4)t11.5 completely suppress the lethality of mod(mdg4)02 homozygotes. One copy of Dvir\mod(mdg4)t11.5 can rescue the lethality of mod(mdg4)02/mod(mdg4)neo129 transheterozygotes, with the degree of rescue depending on the P{Dvir\mod(mdg4)t11.5} line used (95.1% and full viability has been seen). One copy of Dvir\mod(mdg4)t11.5 can rescue the lethality of mod(mdg4)R32/mod(mdg4)02 transheterozygotes. Rescued males show greater viability (91.8% or 95.9% depending on the P{Dvir\mod(mdg4)t11.5} line used) compared to rescued females (26.2% or 37.8% depending on the P{Dvir\mod(mdg4)t11.5} line used). The lethality of mod(mdg4)07/mod(mdg4)02 transheterozygotes is only slightly suppressed by one copy of Dvir\mod(mdg4)t11.5 (12.5% or 5.4% viability has been seen). One copy of Dvir\mod(mdg4)t6.8 partially rescues the lethality of mod(mdg4)02 homozygotes (10.7% viability is seen). Salivary glands and nuclei are reduced in size and show changes in chromosome morphology in these animals at the larval stage. 74.0% viability is seen in mod(mdg4)02 homozygotes carrying two copies of Dvir\mod(mdg4)t6.8. One copy of Dvir\mod(mdg4)t6.8 partially rescues the lethality of mod(mdg4)02/mod(mdg4)neo129 transheterozygotes (34% viability is seen). One copy of Dvir\mod(mdg4)t6.8 partially rescues the lethality of mod(mdg4)R32/mod(mdg4)02 transheterozygous males (52.3% viability is seen), but the lethality of mod(mdg4)R32/mod(mdg4)02 females is not rescued. One copy of Dvir\mod(mdg4)t6.8 does not suppresses the lethality of mod(mdg4)07/mod(mdg4)02 transheterozygotes.

Complementation and Rescue Data

Comments

The lethal phenotype of mod(mdg4)02 is fully complemented by mod(mdg4)Z3-3401, but mod(mdg4)02 fails to complement mod(mdg4)Z3-3401 with respect to X-Y chromosome nondisjunction in male meiosis - transheterozygotes show a high level of X-Y nondisjunction (32.1%).

The lethal phenotype of mod(mdg4)02 is fully complemented by mod(mdg4)Z3-5578 and mod(mdg4)Z3-3298, and mod(mdg4)02 partially or fully complements these alleles with respect to X-Y chromosome nondisjunction in male meiosis - the transheterozygotes show only a low level of X-Y nondisjunction (frequency is indicated in parentheses after each allele); mod(mdg4)Z3-5578 (1.72%) and mod(mdg4)Z3-3298 (2.56%).

Alleles of mod(mdg4) show an allelic series for their effect on In(1)wm4h variegation. From strongest to weakest: mod(mdg4)R32 = mod(mdg4)04 = mod(mdg4)06 = mod(mdg4)07 = mod(mdg4)142Δ32 > mod(mdg4)neo129 = mod(mdg4)02 = mod(mdg4)03 > mod(mdg4)05.
